EEG Signal Processing

Filtering Signal on MATLAB

As in the previous section discussed that the EEG signal has passed through the five stages of the circuit. We are using MATLAB as the real-time simulation and results of EEG signal. By this we can analyze the real-time results and changes of the signal.

We are only using the Simulink part of the MATLAB. The first thing is to install the Arduino package in the MATLAB then a little setting for connecting Arduino board with Simulink. We can use MATLAB for further signal processing. After the signal comes into the MATLAB using Arduino we can use another Low pass filter to achieve better results. We can also reduce all of the extra noise that is still present in the circuit by using another Notch filter in the MATLAB.

Real Time Results on MATLAB

The top Fig- shows the Simulink MATLAB model of Arduino board.

As we can see that the Arduino pin block is connected with the scope. Define the pin in the block and don’t forget to make the MATLAB setting in external mode.

Expected Results

As the results are according to the experiments and simulations. The circuit are working and responding. All the experiments have successfully performed and tested with high accuracy. There was enough noise present in the circuit at earlier stages. By using of 60 Hz notch filter much of the noise has been reduced. The circuit responds successfully. The circuit on hardware may differ in results because of component values but the overall process works fine. The circuit on hardware should respond on the movement of eyes and as according to the process.

SIMULATIONS AND ANALYSIS

All the Simulation have been done on Multisim software. Every stage of the circuit has been simulated and observed.

The fig shows the multisim schematic digram and respose of simulation of the simple low frequency passing filter and notch filter output.
